Search engines

Search engines



               To search the Internet you use what are called
Internet search engines.  These are easily accessed via your Internet browser
(i.e. Microsoft Internet Explorer or Netscape
Navigator/Communicator).  Within the search engine you enter a word or phrase
and it will retrieve documents from the Internet
based on the information you typed in.

Methods of communication

Methods of communication

From electronic mail messages to world wide discussion groups,
communicating with others is the most popular use of theInternet.
The Internet offers electronic versions of familiar types of
communication including Mail, Discussion groups, Telephone
conversations, Radio programs, and teleconferencing.


Internet Service Provider

Internet Service Provider

           An Internet service provider is an organization that maintains a high
speed network of cables connected to the Internet. This organization
usually owns more than one powerful computer that is directly
connected to the network forming the Internet.


Introduction to Email

Introduction to Email




         A hundred years ago a message took 7 days to travel from coast to
coast and even longer to cross the ocean. With the adventof airmail,
that time was cut to 3 or 4 days. Today overnight maildelivery is
available in certain areas, for a hefty surcharge. But  faxing and
electronic mail provide faster and inexpensive delivery of messages.


How e-mail works

How e-mail works






             The way electronic mail works on the Internet is similar to the way the
postal system works. The  addressis the most important part of both
standard letters and e-mail messages. If the address is incorrect the
intended recipient will never see the message.
Issuing a  sendcommand at your computer is similar to placing your
letter in a mailbox. Once you’ve sent your message on  its way, you
cannot retract it.
The postal service collects mail and takes it to the localpost office for
processing and routing. When you send electronic mail, your local post
office reads the e-mail address and either delivers the  message to
another local mail account or sends it to the Internet.
As your letter travels from one post office to another,the postal
service routes it based on the address, so that it continues to move
closer to its destination.


Future of Internet

Future of Internet



               Just the television and the automobile, the Internet  will revolutionize
all aspects of everyday life. Geographic boundaries will fade and with
them, the distance that separates people. Location willno longer be
advantage or a disadvantage. Amenities and services now  common
only in large cities will available to everyone.
             As the Internet continues to evolve, it will change the way we live and
work. Communities will be based on something other than geographic
proximity. We need to define the role of governmentin an electronic
world physical border. While no one knows exactly whatthe future will
bring, the Internet is sure an important role in it.
The Internet is growing rapidly; with hundreds of thousands of new
users getting online each month through Commercial online Services
and Internet access providers.
           The Internet infrastructure is also growing rapidly. Every 30 minutes, a
new network is connected to the Internet. In the future, each person
may be associated with hundreds or even thousands of online devices.
The Internet’s exponential growth presents extreme technological
challenges, as network engineers struggle to keep up with demand.
Today, most people will program their VCRs, start dinner cooking in
the microwave, and activate burglar alarms from anywhere in the
world via the Internet. Every day, entrepreneurs announce new
Internet application, from innovative information gathering services to
voice messaging and videoconferencing. The Internet opens up a
whole way of communicating and doing business. The applications are
limited only by our imaginations. Here are just some ofthe ways that
may be used.
        As the Internet more commercialized, new opportunities  will arise for
both businesses and consumers. Today, many businesses are
beginning to advertise on the Internet.

File Transfer Protocol

File Transfer Protocol

File Transfer Protocol

                File Transfer Protocol is a method of transferring files from one
computer to another. A protocol is a rule or set of rules that have to be
followed by both the client and the server computers so  that
communication can take place between them. It is the same in case of
FTP, the computer that is requesting for a file is the  FTP client, while
the computer, which services the request, is the FTP server and both
of them follow the FTP protocol. Advantages of FTP are Speed, Cost
and Choice.

Birth of Internet?

Birth of Internet?

Birth of Internet?





                          The INTERNET was born in 1969, when a paranoid American military
had nightmares about the primary communication centers  being
bombed out by Russians. To prevent suck occurrence, the ARPA
(Advanced Research Projects Agency) set up four communication
hosts, linking them in such a fashion which would ensurethat even if
one got bombed out. Communication would route aroundthe affected
area and stay alive.
This network called ARPA net quickly grew. This primary service on
ARPA net was electronic mail. It was the first time that emails actually
came into use. In very short time, students began linking their own
campus networks into ARPA net, using a well defined protocol TCP-IP.
This joining of networks was also called inter-networking, and soon the
entire setup was called INTERENT.
In 1973, ARPA net allowed international bodies to the net, and after
that there was no looking back.


CPU

CPU - Central Processing Unit

CPU

CPU





                This part of the computer that executes program instructions is known as the
processor or Central Processing Unit (CPU). In a microcomputer, the CPU is
based on a single electronic component, the microprocessor chip, within the
system unit or system cabinet. The system unit also includes circuit boards,
memory chips, ports and other components. Amicrocomputer’ s system cabinet
will also house disk drives, hard disks, etc., but these are considered separate
from the CPU.



                The CPU has two parts —The Control Unit (CU) and the  Arithmetic Logic Unit
(ALU). In a microcomputer , both are on a single microprocessor chip.



Control Unit (CU)

                The control unit tells the rest of the computer system how to carry out a program’ s
instructions. It directs the movement of electronic signals between memory -which temporarily holds data, instructions and processes information - and the
ALU. It also directs these control signals between the CPU and input/output
devices.


Arithmetic - Logic Unit (ALU)

                Arithmetic Logic Unit, usually called the  ALU, performs two types of operations
- arithmetical and logical.



Web Addresses

Web Addresse

Web Addresse


                    World Wide Web is a network of
electronic files stored on millions
of computers all around the world.
Hypertext links these resources
together.  Uniform Resource
Locators or  URLs are the
addresses used to locate the files.
Every URL is unique and identifies
one specific file.
example:
http://www.du.ac.in
The home page of Delhi
University.



Domain Names

Domain Names

Domain Names


            Every computer that hosts data on the Internet has  a
unique numerical address. For example, the numerical
address for the White House is 198.137.240.100. But
since few people want to remember long strings of
numbers, the  Domain Name System (DNS) was
invented. DNS, a critical part of the Internet's technical
infrastructure, correlates a numerical address to aword.
To access the White House website, you could type its
number into the address box of your web browser. But
most people prefer to use "www.whitehouse.gov." In
this case, the domain name is whitehouse.gov.




The Structure of a Domain Name

The Structure of a Domain Name

The Structure of a Domain Nam



                  A domain name has two or more parts separated by dots and consists of
some form of an organization's name and a three letter or more suffix. For
example, the domain name for IBM is "ibm.com"; the  United Nations is
"un.org." The domain name suffix is known as a  generic top-level
domain (gTLD). It describes the type of organization.
Currently in use gTLDs:


.aero--For the air-transport industry
.biz--Reserved for businesses
.com--For businesses, commercial enterprises
.edu--For educational institutions and universities
.gov--Reserved for United States government agencies
.info--For all uses
.mil--For the United States military
.net--For networks; usually reserved for organizations  such as Internet
service providers
.org--For non-commercial organizations.

What Is JavaScript?

What Is JavaScript?

What Is JavaScript?



           JavaScript is an interpreted(rather than compiled) object-oriented programming  language
that has been developed for use alongside other Web tools. JavaScript does not operate as
a standalone language. It is designed to work together with HTML for creating interactive
Web pages. It is not the same as Java, which is a compiled object-oriented language.
JavaScript is used to write client side applications, which means that JavaScript code
is sent to a user’s computer when a Web page is loaded. The code is then executed, basi-cally line by line, by a JavaScript interpreter included as part of the user’s (client’s) Web
browser. This arrangement minimizes security issues that can arise when a client computer
interacts with the computer that sent the page. It also makes it easy to package an entire
problem, with its own user interface and solution, self-contained within a single document.
But the inability to interact dynamically with information stored on a serverimposes limi-tations on the kinds of tasks that JavaScript can accomplish. 



         It is commonplace to refer to any set of written computer instructions as a “program.”
However, this term is more rigorously applied to a separate entity that can be executed on its
own. Because JavaScript is interpreted rather than compiled, a separately executable entity is
never created. Instead, JavaScript code statements are interpreted and executed one at a time,
essentially “on the fly.” Although this may seem inefficient, there is rarely any discernible
time lag associated with executing JavaScript commands on modern computers.
JavaScript is one of a class of scripting languages whose purpose is to access and mod-ify components of an existing information interface. (Microsoft’s VBScript is another
scripting language.) In this case, the interface is an HTML document. As soon as HTML
documents on the Web evolved from one-way delivery systems for displaying fixed con-tent, something like JavaScript immediately became necessary. One of its first applications
arose from the need to check values entered by users into the fields of HTML forms that
can be sent back to the originator. (Forms are discussed in a later chapter.) JavaScript can
be used to compare input values against an expected range or set of values and to generate
appropriate messages and other actions based on those comparisons.


       JavaScript has evolved into a complete programming language with extensive capabili-ties for manipulating text and handling mathematical operations, useful for a wide range of
computing problems. Possible applications include many self-contained scientific and
engineering calculations. As noted earlier, JavaScript is restricted to problems that do not
need to access external data sources, regardless of whether those sources reside on a local
computer or on a remote server.
